WATER HEATING ANDCIRCULATING APPARATUS..

Patented Oct. 16, 1906.

Application filed August 29, 1906. Serial No. 276.239.

To all whombitmay concern: Be it known that I, PETER J. KOLICH, a citizen of the United States, residing at Oakland, in the-county of Alameda and State ofv 5 California, have invented newand useful Improvements in Water Heating and Circulating Apparatus, of which the following is a specification:

My invention relates to an apparatus- I which is especially designed for heating, cir-' culating, and distributing water.

It consists in the combination of boilerheating coils, distributing and return pi es, and in details of construction which wil be I more fully explained by reference to the accompanying drawings, in which Figure 1 is a vertical section through my apparatus. .Fig. 2 is a reduced plan view of the coils. I

As shown in the drawings, A is a support uponwhich the extension B of the relirninary water-receiver 2 is carried. Tllis portion is adjustably supported in any suitable or desired manner from the part A. The lower receiver 2 is here shown as being con:

. cavo-convexlin form, and water is delivered into it from any source of supply under pressure through apipe 3,. Water rises from the part 2 through aplurality of hollow legs, as

3 shown at 4, and thence it passes into two horizontally-disposed superposed coils 5 and 5; The water enters the outer convolutions of the coils and passes inwardly through the decreasing coils, and at the center the two inner ends of the coils 5 and 5 unite, and

through a pipe 6 the water is delivered into the lower part of the boiler 7. This pipe 6 is closed at the top and may have openings 6 near the bottom in its sides, through which water may escape into the boiler, as shown the arrows. The water is thus introduced into the lower part of the boiler with its temperature somewhat raised by a heater of any suitable description located beneath the coils 5 5 and another series of coils, to be hereinafter described, and all contained within the casing surrounding the lower part of the apparatus. A heater of this description may be illustrated, as at 8. The

water entering and passing up through the legs 4 and up through coils 5 5 is thus heated somewhat and enters the boiler, as previously described, where it isstill subjected to further heat, and the hot water constantly as- 55 cending displaces the cooler water and rises to the top of the boiler. From this point the water is taken through a distributing-pipe, as at 9, .and passes therethrough, having branches which may pass to the kitchen boiler or sink and to radiators by which rooms are heated and bath-rooms and other offices of the house; 10 is a pipe also opening out of the top of the boiler, but extending down into the boiler to a point considerably below the top and into the space occupied by the cooler water. Above the mouth of this pipe the hottest of the water will be found and is drawn from the boiler, as previously described. Through the pipe 10 the cooler water arises, passing through aconnecting- 7o pipe, as at 11, and through a T or cross 12 is returned into a double superposed horizontal coil 13.

By means of a pipe 14 the water which has been'distributed from the upper part of the boiler through the radiators, as previously described, is also returned and passes through the cross or coupling 12 and into the heatingcoil 13. The water passing through this coil from the outside reaches the center and through the connection 13 extends vertically into the other part 13" of the coil, whence it passes outwardly around this coil, still subjected to the heat of the fire below, and is eventually delivered outwardly through 8 5 a pipe 15, which conducts it upwardly and delivers it into the upper part of the boiler, which is thus constantlysupplied with hot water, and this water lies above the mouth of the intake-pipe 10 and may be discharged 0 at any time outwardly through the pipe 9, as previouly described. The water within the boiler is thus subjected to a progressive heating.

Surrounding the'boiler is a jacket, which 5 is composedof double walls, as shown at 16, and the inner wall may be lined with asbestos, so that the whole apparatus is incased with this non-conducting surface and the exterior remains cool. The heat from the fire or burner passing up through the space between the wall 16 and the outside of the boiler 7 provides an additional heating-jacket for the boiler. The top of the jacket 16 closes over the space above the boiler, and within this top is made a concave portion, as shown at 7, approaching the top of the boiler near the center. Through this intermediate space the heat products are carried to the center, where there is a discharge-opening, 1 IO thence pass intov a chamber above the j acket, i

as at 17, eventually escaping therefrom through a discharge pipe or passage; as at B8,-

and to the chimney. This jacket 16 is preferably formed: with an open sea-m at its meeting edges, and it may be provided with hooks and engaging staples or equivalent fastening devices, as shown. at 19, so that it can be detachably secured together and easily removecl for the purpose of obtaining access to: the interior 'for cleaning or other purposes.

A. transparent. mica door 20 may be fixed the side of the casing: opposite the heating apparatus, so that the latter can be readily inspected.

Having thus described my invention, what I. claim, and desire to secure by Letters Patent, is

1. The combination in a water-heater," of

a boiler, a hollow base, means for supplying wat'er' thereto, upwardly-extending water'- legs. in communication with the base, superposed coils, said coils each having its outer convolution connected with onev of said water-legs, and means for providing direct communication between the coils and between said' coils andv the lower part of the boiler;

2. The combination in a water-heater, of a boiler, a hollow base, upwardly-extending water-legs in communication with the base, means for admitting water to the base, superposecl' coils, means? for providing direct communication between the inner ends of the coils and between the coils and the boiler,

each of said coils having; its outer end connected toone ofthe ater-legs.

3'. The combination in a water heater', of

a? hollow base having upwardlyextending. water legs, means for supplying water to said base, a coil havmg superposed reverselyarranged c'onvoliitions, one of' said convolutions' being in communication with one of the water-legs, and the: other convolution being: in communication with the other water leg, and means for providing direct.

communication between the convolutionst of the coil and' between said coil-anal the bottom portion of the boiler.

4;. The combination ot a boiler, a hollow base, means for supplying water to said base, upwardlysextendingwater-legs in communication with the base, superposed coils, the lower ofi which is in communication with one fcommunication with the other water-leg, ,means for providing direct communication 1 between the coils and between said coils and e the lower'part of the boiler, a coil below the first-named coils, cireuiating pipes connecting with opposite ends of the second-named coil, one of said pipes leading from said second coil into the upper'part of' the boiler, and the other circulating-pipe leading from i the boiler into the receiving end of the secondnamed' coil, and a heater in said base. below the second-named coil;

5 The combination of a boiler, a hollow ,1 base, meansfor supplying'water to said base, 5 upwardly-extending water legs in communi- Ecation with the base, superposed coils one 0f which is in communication with one of Esaid water-legs, and the: other 015' which is in ,communication with the other water-leg, lmeans for providing direct communication l between the coils and between said coils and ithe lower part of the boiler, a second coil ,below the first-named coils, a pipe leading if'rom the boiler into the receiving end of ,seeond-named coil, a pipe leading from the delivery end of the second-namedcoil into;

below the first and. second named coils and,

the boiler, and a water distributing and re- ,turn system of pipes connecting with the upper part of the boiler, and having the return-pipe of said system connectingwi'ththe {inlet to the second-named. coil.

In testimony whereofl have" hereuntoset my hand in presence: of' two: subscribing witnesses.
